M-5010 - Troubleshooting: Power

The Standby/On indicator does not light when the ON/STANDBY button is pressed

Bad connections or wiring.

• Check if the power cord is properly connected. If the
  indicator still does not light, turn off the M-5010,
  disconnect the power cord, and contact the dealer
  from whom you purchased this unit.

The unit turns off unexpectedly

• The unit automatically enters standby mode when auto
  standby is activated.
• A speaker cable may have shorted and the protective
  circuit function may have been activated. Make sure bare
  speaker wires are not touching each other or the back
  panel of the unit, then turn the unit on again. If this unit
  does not turn on, immediately unplug the power cord from
  the wall outlet and contact your dealer.
• The protective circuit function may have been activated
  because the temperature of the unit rose abnormally. If
  this happens, then the power will continue to turn off after
  you have turned the unit on again. Make sure the unit has
  plenty of space for ventilation around it, wait for the unit to
  cool down sufficiently, and then try turning it on again.

WARNING:

If smoke, smell or abnormal noise is produced by the unit, unplug the power cord from the wall outlet
immediately and contact the dealer or customer support.
